Hi all! Like everyone else, our university physics department is prepping for online labs. We are utilizing great simulations from several sites, check them out below if you haven't already. We are able to rewrite many of our labs 1:1 conversion to online! Colorado PhETs...of course ...

Hi all, I know qualitatively that charges tend to concentrate on sharp edges of conducting surfaces. I have tried searching online for a mathematical treatment of such a phenomenon, but I cannot find anything that's quite rigorous. I'd appreciate it if someone could guide me towards such...

I can find several resources (in this forum and elsewhere) on pedagogy and teaching tips that are geared towards teachers. Are there any books or resources that provides tips for students of physics, that would make learning more efficient and effective? Examples of the kind of things I am...

Hi all, I am new here. I am unsure if this is the appropriate location for this thread, so please forgive me if I have misplaced it. I am specifically interested in information regarding any qualitative or quantitative observations of biomagnetic fields upon death. It is my supposition that...

Hi everybody, After watching the first lecture by Walter Lewin from MIT, I'm finding hard to follow the part in what he talks about scaling arguments. I've been watching around the Internet for resources to get my head around it but I couldn't find much or maybe I'm not using the right...

Hiya. I'm an undergrad taking my first major's physics course in mechanics (calc based, but not much calc involved thus far), and I am fairly lost. Straight A's in calc 1-3, currently in differential equations math wise and doing well, but having problems with the physics course because it is...

As the title suggests, I'm hoping some of you have some favorite resources for a self-studying novice. I'm sure there are a LOT of places online (and in print) to learn, but if anyone can help point me in the right direction I'd be very appreciative. Cheers!

Hey folks, thought I'd ask the experts for some help here. I know that there are LOTS of online resources to learn Linux Terminal, Microsoft PowerShell, and Python, but I was hoping some of you had some favorites that might make the learning process more efficient (in your opinion, of course)...

I've been very interested in history a long time, read many books and watched many documentaries during the years. I've recently started to watch documentaries on parts of history I did not know very well (the Napoleonic era), and I thought it would be a nice idea to have a thread where those...

Can someone post links to the popularly accepted theories on black holes? Just about all of the information I come across is presented as scientific fact, regardless of how far-fetched some of these ideas may seem, or contradict each other

Like I said, I'm new to Special and General Relativity. It really sucks when I space out for 2 minutes in class and for the next 30 minutes I'm completely lost until the teacher brings up a new topic. I'm looking for supplementary materials (online preferably as I'm away from home) that can...

I want to learn to design a synchronous generator, I search and search but I don’t find nothing to that.

Hi I see there are several articles about how CNN's are used to isolate and classify an object within an nxm rectangular region. While I know how to classify an image into one of p classes, I am not sure how to segment an image into rectangular regions which contain certain objects and, let's...

Are there any resources of questions on the topic of Pell's and non linear Diophantine equations? I am looking for interesting results which are required to be solved. This is for a typical second year undergraduate level. Thanks.

I am looking for a book for learning Python so as to compute matrices, eigenvalues, eigenvectors, divergence, curl (i.e vector calculus). If you also have online recommendations please feel free to write them.

Hi All, i have been mostly into the structural analysis domain ...now want to explore the world of sound waves/Acoustics. What should be the best way to start with? Regards Kapil

I'm having quite a bit of difficulty in my college's intro honors, calc-based physics class. I want to find some good resources, either online or text, to assist with learning the material. The issue I'm having is that most resources I find are either not in depth enough, or they're just as...

Hi I am trying to learn how to manipulate 3D files like obj or stl using programming (I primarily use Python, but also know Javascript). Which resources can I use to learn this?

I need a better understanding of limit swtiches and servo motors than I'm getting from Wikipedia :) Any website/textbook recommendations? (My background is physics.) TIA!

Hello! I'm currently working on a project in which I need to make an animated visualization demonstrating the physical changes and luminosity changes of a star with non radial stellar pulsations. This visualization has to be based on real or theoretical data or a real or theoretical model but I...

I have recently started studying multivariable calculus and I cannot quite visualise the concepts.Problem solving is not a problem but I want a true understanding of the concepts.Which book or online resources are great at developing visualisation in this course?

What is the most motivating way in introduction to Pythagorean triples to undergraduate students? I am looking for an approach that will have an impact. Good interesting or real life examples will help. Is there any resources for this?

When we see with open eyes or in visible range of wavelength of e.m. wave we see black space containing some star...but if we see the space in other range of wavelength of the e.m. wave what will we see?? Also why the space is black?? Which matel we find in space mostly? Can we extract those...

For those who might need a relatively simple electronic device for a project like relay control, frequency to voltage converters, voltage to current and current to voltage converter, small signal amplifiers, signal averaging and many others using cheap op-amps, I recommend "How to Build and...

I had an interesting thought tonight, but my Google-foo is failing me so far. I learned Spanish as a second language in high school, and have lost most of that skill over the years. I learned a fair bit of Japanese as an Army bratt stationed in Yokohama in the late 1960s with my family, but...

I need some good book(s) or other resources from where I can learn UV-Visible Spectroscopy. Besides explaining the mathematical and theoretical intricacies, it should also mention the practical aspects. If you have read any and found it good, please recommend it.

Does anyone know of any resources on questions on primitive roots and order of a modulo n? They need to be suitable for elementary number theory course. (These could be interesting results and challenging ones).

Hello I am planning to apply for some academic positions (lecturer, assistant professor level and equivalent) in US, Canada and Australia. My field is nano-optics and applied electrodynamics. Can anyone suggest websites where such positions would be advertised? I have googled of course. I get...

Some background info: I am an international student that is currently studying at a supposedly prestigious university (Top 20 in QS and Times Higher Education ranking). As part of my major requirement, I am taking an EM module. The problem is, my forte is not really physics (I am an IBO...

I'm working on a description of ultracold chemistry and one of the modes of tuning the interactions involves Feshbach resonance. Right now I'm referring to Feshbach's original piece and accompanying it with Pethick and Smith book titled Bose-Einstein Condensation in Dilute Gases, specifically...

Hi, Does anyone know of any online groups/forums of primarily logicians and strategists that I can use to help me do a long walk through a complex personal problem? I am in urgent need of someone with better judgement than myself that can take their time to build coherence before dismissing...

There has been much debate about SETI (Search for Extra-Terrestrial Intelligence) and whether or not we should try to contact ET. Some (Including Stephen Hawking) have argued it is a bad idea to announce "We're here" as the aliens would likely come here, squash us like an ant hill in Africa...
